Hi Chris,
Here is a sample about email (or download) a copy of the slide as PNG.
In this sample, the first slide contains two text boxes for users input their name and their email address (which will be used to send email).
The second slide contains the certificate. Because of some technical limits, this slide should only contain images and texts. Please take a look at On Load event of this slide - here we add custom javascript code for download or send email action.
We use Google Script to send the email. You can see the sample code here:
Here is the guide for deploying a Google Script as a web app:

Hope this helps,
